Background: Quality indicators are crucial in evaluating and comparing the quality of healthcare services. In the case of congenital heart disease, transition programmes for adolescents have been recommended to ensure uninterrupted healthcare and lifelong care. It is necessary to establish quality indicators in order to facilitate the evaluation of programme quality and to allow comparison between different centres. The objective of this study is therefore to develop a set of quality indicators for the transition of adolescents with congenital heart disease. Methods: The RAND/UCLA appropriateness method was employed in a four-step process to develop a set of quality indicators. First, a literature search was conducted on the dimensions of transitional care, based on which a preliminary set of quality indicators was developed. Second, experts were contacted, and an expert panel was established. Third, the panel members were asked to rate the appropriateness of the quality indicators in a two-round process. Finally, in the fourth step, we evaluated the data by measuring the median and Disagreement Index. Results: The expert panel consisted of 16 members, congenital cardiologists, nurses, transition experts, patients and research experts. The preliminary set of quality indicators comprised 16 items, categorized in process and structure criteria. Based on the panel's feedback, the set was refined to 12 quality indicators, which were rated as relevant and feasible. Conclusions: This study represents the first attempt to develop quality indicators for transitional care services for adolescents with congenital heart disease. The set of 12 quality indicators was developed based on existing evidence and expert opinion. Further testing is needed to assess the feasibility of these quality indicators in daily practice. If successfully implemented, these quality indicators could allow comparison and facilitate benchmarking of transitional care services for adolescents with congenital heart disease.

Aims: Patients with adult congenital heart disease (ACHD) are a potentially vulnerable patient cohort in case of COVID-19. Some cardiac defects may be associated with a poor COVID-19 outcome. Risk estimation in ACHD is currently based on expert opinion. The aim of this study was to collect clinical outcome data and to identify risk factors for a complicated course of COVID-19 in patients with ACHD.Methods: Twenty-five ACHD centres in nine European countries participated in the study. Consecutive patients with ACHD diagnosed with COVID-19 presenting to one of the participating centres between 27 March and 6 June 2020 were included. A complicated disease course was defined as hospitalisation for COVID-19 requiring non-invasive or invasive ventilation and/or inotropic support, or a fatal outcome.Results: Of 105 patients with a mean age of 38±13 years (58% women), 13 had a complicated disease course, of whom 5 died. In univariable analysis, age (OR 1.3, 95% CI 1.1 to 1.7, per 5 years), ≥2 comorbidities (OR 7.1, 95% CI 2.1 to 24.5), body mass index of >25 kg/m2 (OR 7.2, 95% CI 1.9 to 28.3) and cyanotic heart disease (OR 13.2, 95% CI 2.5 to 68.4) were associated with a complicated disease course. In a multivariable logistic regression model, cyanotic heart disease was the most important predictor (OR 60.0, 95% CI 7.6 to 474.0).Conclusions: Among patients with ACHD, general risk factors (age, obesity and multiple comorbidities) are associated with an increased risk of complicated COVID-19 course. Congenital cardiac defects at particularly high risk were cyanotic lesions, including unrepaired cyanotic defects or Eisenmenger syndrome. [ABSTRACT FROM AUTHOR]

We are witnessing an unparalleled pandemic caused by the novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) associated with coronavirus disease 2019 (COVID-19). Current data show that SARS-CoV-2 results in mild flu-like symptoms in the majority of healthy and young patients affected. Nevertheless, the severity of COVID-19 respiratory syndrome and the risk of adverse or catastrophic outcomes are increased in patients with pre-existing cardiovascular disease. Patients with adult congenital heart disease (ACHD)—by definition—have underlying cardiovascular disease. Many patients with ACHD are also afflicted with residual haemodynamic lesions such as valve dysfunction, diminished ventricular function, arrhythmias or cyanosis, have extracardiac comorbidities, and face additional challenges regarding pregnancy. Currently, there are emerging data of the effect of COVID-19 on ACHD patients, but many aspects, especially risk stratification and treatment considerations, remain unclear. In this article, we aim to discuss the broad impact of COVID-19 on ACHD patients, focusing specifically on pathophysiology, risk stratification for work, self-isolation, hospitalization, impact on pregnancy, psychosocial health, and longer-term implications for the provision of ACHD care.

Irrespective of initial treatment for congenital heart disease (CHD) in childhood, CHD is a lifelong condition, leaving patients at risk for complications. To support uninterrupted, age- and development-based care for young persons with CHD, guidelines and consensus papers emphasise the need for formal transition programmes, including transfer to adult CHD (ACHD) clinics. Here, we surveyed existing transfer and transition programmes in European ACHD centres. Our aims were to provide a contemporary view of transitional care for patients with CHD and to evaluate progress over the last decade. We conducted a descriptive, cross-sectional survey in 96 ACHD centres in Europe. A specific survey form was developed that sampled the practices of transfer and/or transition. We used a transfer-transition index to quantify adherence to quality indicators of successful transfer and transition. Of the 96 ACHD centres, 40 (41.7%) offered a formal transition, and 85 (88.5%) had structured transfer from paediatric to ACHD care. Although 31% of the centres performed at a 'good' level on the transfer-transition index, only 4 (4.2%) satisfied all criteria. Most centres with a transition programme offered education and support through a dedicated transition specialist, who was a master's-prepared nurse in most centres. A minority of the ACHD centres offered a flexible transition process, starting at least two years before transfer. Nearly half of the included ACHD centres offered a formal transition programme, and almost 90% offered structured transfer. Despite some improvements since 2009, most of the programmes lacked an age- and development-based approach. • The majority of CHD centres in Europe offer a structured transfer from paediatric to adult care. • Although the number of centres with formal transition increased over time, time, only a minority follows the recommendations to the fullest maximum. • All transition programmes included a dedicated transition specialist; the role is often taken up by nurses.

Objective: Pregnancy in women with aortic coarctation (CoA) has an estimated moderately increased risk (mWHO II-III) of adverse cardiovascular, obstetric or fetal events, but prospective data to validate this risk classification are scarce. We examined pregnancy outcomes and identified associations with adverse outcomes.Methods: Pregnancies in women with CoA were selected from the worldwide prospective Registry of Pregnancy and Cardiac Disease (ROPAC, n=303 out of 5739), part of the European Society of Cardiology EURObservational Research Programme. The frequency of and associations with major adverse cardiac events (MACE) and hypertensive disorders (pregnancy-induced hypertension, (pre-)eclampsia or haemolysis, elevated liver enzymes and low platelets syndrome) were analysed.Results: Of 303 pregnancies (mean age 30 years, pregnancy duration 39 weeks), 9.6% involved unrepaired CoA and 27.1% were in women with pre-existing hypertension. No maternal deaths or aortic dissections occurred. MACE occurred in 13 pregnancies (4.3%), of which 10 cases were of heart failure (3.3%). Univariable associations with MACE included prepregnancy clinical signs of heart failure (OR 31.8, 95% CI 6.8 to 147.7), left ventricular ejection fraction <40% (OR 10.4, 95% CI 1.8 to 59.5), New York Heart Association class >1 (OR 11.4, 95% CI 3.6 to 36.3) and cardiac medication use (OR 4.9, 95% CI 1.3 to 18.3). Hypertensive disorders of pregnancy occurred in 16 (5.3%), cardiac medication use being their only predictor (OR 3.2, 95% CI 1.1 to 9.6). Premature births were 9.1%, caesarean section was performed in 49.7% of pregnancies. Of 4 neonatal deaths, 3 were after spontaneous extreme preterm birth.Conclusions: The ROPAC data show low MACE and hypertensive disorder rates during pregnancy in women with CoA, suggesting pregnancy to be more safe and better tolerated than previously appreciated.

Survival prospects in adults with congenital heart disease (CHD), although improved in recent decades, still remain below expectations for the general population. Patients and their loved ones benefit from preparation for both unexpected and predictable deaths, sometimes preceded by a prolonged period of declining health. Hence, advance care planning (ACP) is an integral part of comprehensive care for adults with CHD. This position paper summarizes evidence regarding benefits of and patients' preferences for ACP and provides practical advice regarding the implementation of ACP processes within clinical adult CHD practice. We suggest that ACP be delivered as a structured process across different stages, with content dependent upon the anticipated disease progression. We acknowledge potential barriers to initiate ACP discussions and emphasize the importance of a sensitive and situation-specific communication style. Conclusions presented in this article reflect agreed expert opinions and include both patient and provider perspectives.

Objective: Self-efficacy is a known predictor of patient-reported outcomes in individuals with acquired diseases. With an overall objective of better understanding patient-reported outcomes in adults with congenital heart disease, this study aimed to: (i) assess self-efficacy in adults with congenital heart disease, (ii) explore potential demographic and medical correlates of self-efficacy and (iii) determine whether self-efficacy explains additional variance in patient-reported outcomes above and beyond known predictors. Methods: As part of a large cross-sectional international multi-site study (APPROACH-IS), we enrolled 454 adults (median age 32 years, range: 18–81) with congenital heart disease in two tertiary care centres in Canada and Switzerland. Self-efficacy was measured using the General Self-Efficacy (GSE) scale, which produces a total score ranging from 10 to 40. Variance in the following patient-reported outcomes was assessed: perceived health status, psychological functioning, health behaviours and quality of life. Hierarchical multivariable linear regression analysis was performed. Results: Patients’ mean GSE score was 30.1 ± 3.3 (range: 10–40). Lower GSE was associated with female sex (p = 0.025), not having a job (p = 0.001) and poorer functional class (p = 0.048). GSE positively predicted health status and quality of life, and negatively predicted symptoms of anxiety and depression, with an additional explained variance up to 13.6%. No associations between self-efficacy and health behaviours were found. Conclusions: GSE adds considerably to our understanding of patient-reported outcomes in adults with congenital heart disease. Given that self-efficacy is a modifiable psychosocial factor, it may be an important focus for interventions targeting congenital heart disease patients’ well-being. [ABSTRACT FROM AUTHOR]

Objective: High altitude-related hypoxia induces pulmonary vasoconstriction. In Fontan patients without a contractile subpulmonary ventricle, an increase in pulmonary artery pressure is expected to decrease circulatory output and reduce exercise capacity. This study investigates the direct effects of short-term high altitude exposure on pulmonary blood flow (PBF) and exercise capacity in Fontan patients.Methods: 16 adult Fontan patients (mean age 28±7 years, 56% female) and 14 matched controls underwent cardiopulmonary exercise testing with measurement of PBF with a gas rebreathing system at 540 m (low altitude) and at 3454 m (high altitude) within 12 weeks.Results: PBF at rest and at exercise was higher in controls than in Fontan patients, both at low and high altitude. PBF increased twofold in Fontan patients and 2.8-fold in the control group during submaximal exercise, with no significant difference between low and high altitude (p=0.290). A reduction in peak oxygen uptake at high compared with low altitude was observed in Fontan patients (22.8±5.1 and 20.5±3.8 mL/min/kg, p<0.001) and the control group (35.0±7.4 and 29.1±6.5 mL/min/kg, p<0.001). The reduction in exercise capacity was less pronounced in Fontan patients compared with controls (9±12% vs 17±8%, p=0.005). No major adverse clinical event was observed.Conclusions: Short-term high altitude exposure has no negative impact on PBF and exercise capacity in Fontan patients when compared with controls, and was clinically well tolerated.Trial Registration Number: NCT02237274: Results.

Atrial septal defects (ASDs) are one of the most frequent congenital cardiac malformations, accounting for about 8-10% of all congenital heart defects. The prevalence of pulmonary arterial hypertension (PAH) in adults with an ASD is 8-10%. Different clinical PAH scenarios can be encountered. At one end of the spectrum are adults with no or only mild pulmonary vascular disease and a large shunt. These are patients who can safely undergo shunt closure. In the elderly, mild residual pulmonary hypertension after shunt closure is the rule. At the other end of the spectrum are adults with severe, irreversible pulmonary vascular disease, shunt reversal and chronic cyanosis, that is, Eisenmenger syndrome. These are patients who need to be managed medically. The challenge is to properly classify ASD patients with PAH falling in between the two ends of the spectrum as the ones with advanced, but reversible pulmonary vascular disease amenable to repair, versus the ones with progressive pulmonary vascular disease not responding to shunt closure. There are concerns that adults with progressive pulmonary vascular disease have worse outcomes after shunt closure than patients not undergoing shunt closure. Due to the correlation of pulmonary vascular changes and pulmonary hemodynamics, cardiac catheterization is used in the decision-making process. It is important to consider the hemodynamic data in the context of the clinical picture, the defect anatomy and further noninvasive tests when evaluating the option of shunt closure in these patients.

Abstract: The steadily growing number of adults with congenital heart disease has led with some delay to an increase of specialized programs dedicated to the care of these patients. Still, in many countries the prevalence of congenital heart disease in adults is not known, nor the number of adults requiring specialized care. By extrapolating the results of epidemiological studies on the population in Europe and North America, only half or even less of all adults with moderate or complex congenital heart disease is currently under follow-up in specialized centers. Lapse of appropriate medical care in adults with congenital heart disease is associated with unnecessary morbidity and an increased likelihood of the need for urgent interventions. In order to improve medical care for adults with moderate or complex congenital heart disease, the number of patients with specialized follow-up in congenital cardiac clinics has to increase. One approach is to avoid lapses of care in patients already followed by a pediatric or adult congenital heart disease center. Therefore, congenital heart disease clinics should try to identify among their patients the ones at risk for lost to follow-up, and focus some of their efforts on measures to increase the awareness for life-long medical care among these patients. Characteristics of the adult congenital cardiac patient at high risk of inappropriate medical follow-up include having few interventions in early life despite a complex cardiac defect, being born in an earlier decade, receiving no specific follow-up recommendations, and having no education about defect- or surgery-related sequelae or residual lesions. Implementation of a structured transition program, teaching patients about their heart defect and the consequences of repair or palliation in earlier life, establishing a continuity of care within the congenital cardiac clinic, optimizing organization and communication between different care-givers, and encouraging patients to play an active role regarding their personal health care, are some of the recommendations on how we should try to avoid another generation of adult congenital heart disease patients from being lost to follow-up.

Objective A consequence in patients with d-transposition of the great arteries (d-TGA) and tetralogy of Fallot (TOF) is right ventricular hypertrophy (RVH) and right ventricular failure. Myocardial contrast echocardiography (MCE) permits the determination of the myocardial microvascular density reflected by the relative myocardial blood volume (rBV; ml/ml). This study was conducted to elucidate the relationship between RVH and myocardial microvascular changes by quantitative MCE in patients with d-TGA and TOF. Methods Three groups of individuals were included in the study: 22 patients with d-TGA, 18 patients with TOF and 22 healthy individuals (controls). MCE was performed at rest and during adenosine-induced hyperaemia. rBV and myocardial blood flow (MBF; ml/min per gram) were derived from steady state and refill sequences of ultrasound contrast agent. Results Hyperaemic septal rBV differed significantly between the groups and was highest in controls: d-TGA 0.141±0.060 ml/ml, TOF 0.134±0.080 ml/ml, controls 0.189±0.074 ml/ml, p=0.005. Myocardial blood flow reserve (MBFR), that is the ratio of hyperaemic to baseline MBF, differed significantly between the groups and was lowest in d-TGA (2.68±1.13) versus TOF (3.37±1.57) and controls (4.22±1.17, p=0.001). Hyperaemic septal rBV, MBF and MBFR showed a significant correlation with right ventricular systolic function as determined by tricuspid annular plane systolic excursion. Conclusions Right ventricular myocardial microvascular density of the septal wall in d-TGA and TOF patients with RVH due to pressure and/or volume overload is reduced. This appears to be related to a reduced myocardial perfusion reserve and impaired right ventricular systolic function. [ABSTRACT FROM AUTHOR]

Background: Adult patients with repaired tetralogy of Fallot (rTOF) often have diminished exercise capacity. The primary objective of this study was to examine whether abnormalities of biventricular function play a role in exercise limitation in patients with rTOF. Methods: This was a retrospective review of 99 adult patients with rTOF. Right ventricular (RV) and left ventricular (LV) function were assessed echocardiographically using the myocardial performance index (MPI). Maximal oxygen consumption (VO2 Max) was measured during a level 1 cardiopulmonary exercise test. Results: The mean age of the cohort was 34 ± 11 years (50% females). Although most of the patients reported good functional capacity, the peak Vo 2max was decreased at 22 ± 6 mL/kg per minute (66% ± 13% predicted Vo 2max for age and sex). The mean RV and LV MPI were 0.30 ± 0.07 and 0.42 ± 0.09, respectively. In the multivariate model, higher RV MPI (P = .04) and LV MPI (P = .005) values, representing impaired ventricular function, were associated with diminished Vo 2max. There was a significant correlation between the RV and LV MPI (r = 0.54, P = .001). Conclusions: Impairment of RV and LV function, as measured by MPI, is associated with diminished exercise capacity in patients with repaired tetralogy of Fallot. Furthermore, there is a linear relationship between the RV and LV function suggesting that ventricular interactions are contributing to the limited exercise capacity in this group of patients. Strategies aimed at preserving biventricular function or improving adverse ventricular interactions could help to improve functional capacity in these patients. [Copyright &y& Elsevier]

Adults with repaired tetralogy of Fallot and significant chronic pulmonary regurgitation are at risk for progressive right ventricular (RV) dilatation and dysfunction. The assessment of RV function is important in the management in these patients. There is still a lack of an adequate geometric model to quantify RV function by echocardiography. The myocardial performance index (MPI) is a nonvolumetric method to quantify global ventricular function. In this study, the accuracy of MPI obtained by echocardiography to quantify RV function was assessed in 57 adults with repaired tetralogy of Fallot. The MPI measurement was compared with the RV ejection fraction (EF) derived by cardiac magnetic resonance imaging. There was a negative linear correlation between the MPI and the RVEF (r = 0.73, p <0.001). A MPI cutoff of ≥0.40 had a sensitivity of 81% and a specificity of 85% to diagnose a RVEF <35%. A MPI cutoff of <0.25 had a sensitivity of 70% and a specificity of 89% to identify patients with RVEFs ≥0.50. In a multivariate regression model, the MPI was not affected by the degree of pulmonary regurgitation, the presence of tricuspid regurgitation, or the QRS duration. In conclusion, the Doppler-derived MPI is a simple and reliable method for the evaluation of RV systolic function in adults with repaired tetralogy of Fallot. [Copyright &y& Elsevier]

Abstract: Altered myocardial perfusion is frequent in patients with congenital heart disease. Measurement of myocardial blood flow per gram of myocardium at rest and during hyperemia is the most robust method to evaluate myocardial perfusion in absolute terms. So far, most studies in congenital heart disease patients used positron emission tomography to evaluate absolute myocardial blood flow. With the recent advances in contrast echocardiography, we have now a more easily applicable but similarly solid method at hand to assess myocardial perfusion in different clinical scenarios. Myocardial contrast echocardiography has proven its clinical and scientific value in coronary artery disease patients. In this review, we discuss the merits of myocardial perfusion assessment in patients with a systemic right ventricle, a univentricular heart physiology, and tetralogy of Fallot. We outline how myocardial contrast echocardiography can improve our understanding of ventricular function. We have to admit that its clinical value remains to be elucidated. For most congenital defects, the impact of impaired myocardial perfusion on ventricular function and clinical outcome is still poorly investigated. Myocardial contrast echocardiography can contribute to fill this gap. [Copyright &y& Elsevier]

Clinical guidelines emphasise the need for specialised adult congenital heart disease (ACHD) programmes. In 2014, the working group on Grown-up Congenital Heart Disease of the European Society of Cardiology (ESC) published recommendations on the organisation of specialised care for ACHD. To appraise the extent to which these recommendations were being implemented throughout Europe, we assessed the number of patients in active follow-up and available staff resources in European ACHD programmes. We conducted a descriptive, cross-sectional, paper-based survey of specialised ACHD centres in Europe in late 2017 concerning their centre status in 2016. Data from 96 ACHD centres were analysed. We categorised ACHD programmes into seven different centre types based on their staff resources and composition of interdisciplinary teams. Only four centres fulfilled all medical and non-medical staffing requirements of the ESC recommendations. Although 60% of the centres offered all forms of medical care, they had incomplete non-medical resources (i.e., specialised nurses, social workers, or psychologists). The participating centres had 226,506 ACHD patients in active follow-up, with a median of 1500 patients per centre (IQR: 800-3400). Six per cent of the patients were followed up in a centre that lacked a CHD surgeon or congenital interventional cardiologist. A minority of European ACHD centres have the full recommended staff resources available. This suggests that as of 2016 either ACHD care in Europe was still not optimally organised, or that the latest ESC recommendations were not fully implemented in clinical practice. • Overview of the structure and staffing of ACHD centres in Europe. • Steady increase in the number of centres but not in patient numbers per centre. • High variability within centres between patient load and staff resources. • Poor adherence in staff resources to the current recommendations.

The number of adults with congenital heart disease (CHD) has increased markedly over the past few decades as a result of astounding successes in pediatric cardiac care. Nevertheless, it is now well understood that CHD is not cured but palliated, such that life-long expert care is required to optimize outcomes. All countries in the world that experience improved survival in CHD must face new challenges inherent to the emergence of a growing and aging CHD population with changing needs and medical and psychosocial issues. Founded in 1992, the International Society for Adult Congenital Heart Disease (ISACHD) is the leading global organization of professionals dedicated to pursuing excellence in the care of adults with CHD worldwide. Recognizing the unique and varied issues involved in caring for adults with CHD, ISACHD established a task force to assess the current status of care for adults with CHD across the globe, highlight major challenges and priorities, and provide future direction. The writing committee consisted of experts from North America, South America, Europe, South Asia, East Asia, and Oceania. The committee was divided into subgroups to review key aspects of adult CHD (ACHD) care. Regional representatives were tasked with investigating and reporting on relevant local issues as accurately as possible, within the constraints of available data. The resulting ISACHD position statement addresses changing patterns of worldwide epidemiology, models of care and organization of care, education and training, and the global research landscape in ACHD.

Abstract: Background: Due to better early and long-term outcome, the increasing population of grown-ups with congenital heart disease (GUCH) brings up unexpected quality of life (QoL) issues. The cardiac lesion by itself is not always the major problem for these patients, since issues pertaining to QoL and psychosocial aspects often predominate. This study analyses the QoL of GUCH patients after cardiac surgery and the possible impact of medical and psychosocial complications. Patients and methods: A questionnaire package containing the SF-36 health survey (health related QoL), the HADS test (anxiety/depression aspects) and an additional disease specific questionnaire was sent to 345 patients (mean 26±11 years) operated for isolated transposition of the great arteries (TGA), tetralogy of Fallot (TOF), and ventricular septal defect (VSD). The scores were compared with age- and gender-matched standard population data and in relation to the underlying congenital heart disease (CHD). Results: In all SF-36 and HADS health dimensions the GUCH patients showed excellent scores (116±20), which are comparable to the standard population (100±15), regardless of the initial CHD (p =0.12). Eighty-two percent of the patients were found to be in NYHA class I and 83% patients declared that they do not consider their QoL to be limited by their malformation. Complications like reoperations (p =0.21) and arrhythmias (p =0.10) do not show significant impact on the QoL. The additional questionnaire revealed that 76% of adult patients have a fulltime job, 18% receive a full or partial disability pension, 21% reported problems with insurances, most of them regarding health insurances (67%), and 4.4% of adult patients declared to have renounced the idea of having children due to their cardiac malformation. Conclusion: QoL in GUCH patients following surgical repair of isolated TOF, TGA and VSD is excellent and comparable to standard population, this without significant difference between the diagnosis groups. However, these patients are exposed to a high rate of complications and special psychosocial problems, which are not assessed by standardized questionnaires, such as the SF-36 and HADS. These findings highlight the great importance for a multidisciplinary and specialized follow-up for an adequate management of these complex patients. [Copyright &y& Elsevier]
